If we look at the sugar-water phase diagram;
at 80° C : 26% of water will dissolve 74% of sugar
C = m / ( m + 1000 g ) · 100
74 = m / ( m + 1000 g ) · 100
0.74 = m / ( m + 1000 g )
m = 0.74 · ( m + 1000 g )
m = 0.74 m + 740 g
m - 0.74 m = 740 g
0.26 m = 740 g
m = 740 g : 0.26
m = 2,846.15 g ≈ 2,846 g
Answer:
m ( sugar ) = 2,846 g.
When the pressure increases, the area decreases.
When the area increases, the pressure decreases.
Answer:
Potassium is an element, with the symbol K
Explanation:
An element is something that cannot be broken down any further, for example, calcium, its Ca.
A compound is when you bond two or more elements. Compounds can be broken down into its original elements, for example, H₂O, it contains two atoms of hydrogen and one atom of oxygen (both hydrogen and oxygen are elements).
Answer:
The mass of a pure substance represents a specific number of pure substance 'molecules', as defined by molecular weight. The relative atomic mass (atomic weight) in grams/mole (g/mol) is the molar mass of a substance, which means it is the mass of one mole of that substance.
